WHEEL-HUB.

Specification of Letters Patent.

Patented Apr. 23, 1912.

Application filed August 4, 1910. Serial No. 575,413.

To all whom it may concern:

Be it known that I, J OHN J. MCGUIRE, a citizen of the United States,and a resident of the city of New York borough of Manhattan, in thecounty and State of New York, have invented a new and ImprovedVVheel-Hub, of which the following is a full, clear, and exactdescription.

Among the principal objects which the present invention has in view are:to provide dustproof chambers for supplying oil to the axle journal andto prevent the admission of dust or grit thereto; to provide areinforcing metal protective shell for the hub and an auxiliary liningfor the oil containing receptacle thereof, constructed and arranged toprevent the seepage of oil between said shell and the body of the hub.

One embodiment of the present invention is disclosed in the structureillustrated in the accompanying drawings, in which like characters ofreference denote corresponding parts in all the views, and in which-Figure 1 is a vertical longitudinal section of a hub constructed andarranged in accordance with the present invention; Fig. 2 is a verticalcross section taken on the line 22 in Fig. 1; and Fig. 8 is a verticalcross section taken on the line 33 in Fig. 1.

When constructed in accordance with the present invention the woodenbody or filler 8 is shaped substantially as shown in longitudinalsection in the drawings, and is covered at both ends by metal casings 9and '10. The hub is provided with a journal box 11 secured in the body 8in the usual manner. The box 11 is elongated to extend slightly beyondthe ends of the perforation formed in the body 8 for the same. The endedges of the box 11 form thrust bearings for a collar 12 and a nut 13.

The casing 9 is extended to form a cylindrical box-like portion 14, theouter edge whereof is provided with an internally threaded portion 15.The threads provided on the portion 15 are constructed to receive thethreaded flange 16 of a cap nut 17. The extension of the portion 14: issuflicient to form a chamber at the outside of the nut 13 and the screwthreaded end of the axle 18. It is within this chamber that the loosepacking 19 is placed. The packing 19 is supersaturated with oil or othersuitable lubricant. It is to prevent the exudation or seepage of oilfrom the box formed by the portion 14 between the body or filler 8 andthe casing 9, that there is provided a metal lining 20. The lining 20 isprovided with a central opening adapted to neatly fit and receive thebase flange of the nut 13.

The casing 10 is provided with an extended portion 21, to serve as acollar for the rear of the filler 8. The filler 8 is recessed at therear to form a box-like receptacle for the collar 12. To dust proof thejoint between the collar 12, the box 11 and axle 18, I have provided acup ring 22. The ring 22 is provided with a series of ear likeprojections 23 provided to receive screws 24. The screws 24 when driventhrough the cars 23 are extended into the filler 8 in holding engagementtherewith. The cup ring 22 isprovided with suitable loose packing 25,which is saturated with oil to wipe the collar 12 and to prevent theadmission of grit or dust therebetween. The packing 25 further servesthe purpose of arresting any of the oil which may pass through thebearing formed for the journal 18 by the box 11, thus preventing theunsightly and disagreeable oil stains and coagulations on the rear ofthe hub. It will be understood that the ring 22 is placed in positionafter the wheel having the hub thus constructed is mounted in position.

During the employment of a hub thus constructed and arranged, the oilingof the axle 18 is performed by removing the cap nut 17 andsupersaturating the packing 19 contained in the portion 14.

The lining 20 I prefer to secure in position by screws 26, as shown inFig. 1 of the drawings.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. A wheel hub, comprising a metal hubcasing having an externally projected boxlike end portion, said portionhaving formed adjacent the outer edge thereof an internal screw thread;a cap for said boxlike portion provided with a peripheral screw threadto engage the screw thread in said box-like portion, and a box-likelining having cylindrical and radial flanges, the former constructed toform a seat for said cap and the latter to form a seat for the holdingnut of said hub, said lining being removable from said hub.

2. In a wheel hub, an oil box having provided adjacent the open endthereof a screw thread; a lining for said boxhaving cylin- In testimonywhereof I have signed this speorficatlon in the presence of two sub- 10scribing Witnesses.

drical side Walls and a bottom portion, said bottom portion beingperforated to extend about the axle Within said box and to rest underthe holding nut of said axle; and a screw threaded closure cap for saidbox threaded to engage the screw threads of said box and to seat on theouter edge of said lining.
